I have never been able to understand (I am not at genius level yet

) the price/cost of housing in Indonesia eg. perhaps 2 working middle class people could afford a mortgage on a house for 400 million. But it is difficult in may areas to find houses for these prices. Even recently my wife noticed someone she knows post a 100 sq metre house, in Jogja , 3 bedroom 2 bath for 1.2 billion. But most people in Indonesia can not afford this so what is driving these prices? Who owns all these properties?
Just to clarify:
Min salary eg. 2 jt x 12 = 24 jt / year x 10 years mortgage =240 jt x 2 people 480 jt. For a couple on MIN SALARY not middle working class!
Here in Cikarang the MIN SALARY is around 3+ jt. so = 360 x 2 people 720 jt for 10 years.
Middle class is starting maybe somewhere like 10 jt / per month? (this is my guess only) 10 jt x 12 (months) x 10 years = 1,2 M / one person working.
I can see a lot of development sings here in Cikarang with prices 400-600-800 jt. Eg. Meikarta 120 jt you can own an apartament or with 2jt. cicilan/bulan. Not sure about square meters probably very small.
The house you have mentioned will be bough by a doctor, accountant /IT professional in mid size international company, gov. official, some business owner. Not by a forklift driver, truck driver ect...
"But most people in Indonesia can not afford this so what is driving these prices? Who owns all these properties?"
And....?
Who owns houses for workers in UK those that they sell later on as new development - private investors, developers, funds, goverment.
Can a non-skilled factory worker in UK on 7.30 pound/hrs buy 1 mln pound property? No, why? I don't think he can even afford to get a 200 000 property. More likely they will aim to get 90-120 000 max. If they will not end up in social housing or renting out flat/house all their life. So what is driving those absurd property prices in UK? Maybe the same things that drive prices over there will apply here in Indonesia.
